jetson配置yolov5(tensor加速版）出现的问题（killed+tensor+~)
1.在cmake生成engine引擎文件时，出现一系列报错

1.1 原因分析
根据大佬tensorrtx/yolov5 at yolov5-v4.0 · wang-xinyu/tensorrtx
的包中，他的配置条件是在tensoRT7.x的环境下部署的，而我的TensorRT是8.x版本的，这就很那个了。
1.2解决方法
https://github.com/wang-xinyu/tensorrtx/tree/b7a754e2de7b21989a868f2740b82d8417dad1cf/yolov5
把上述包里面的文件下下来，然后把之前yolov5文件下的文件全部替换成能支持tensoRT8的，然后就ok!
2.在jetson运行yolo5时会报错AttributeError: ‘Upsample‘ object has no attribute ‘recompute_scale_factor
解决方法：参考大神YOLOV5 | AttributeError: ‘Upsample‘ object has no attribute ‘recompute_scale_factor‘ 问题解决 亲测有效_yolov5-lite export.py attributeerror: 'upsample' o-CSDN博客
真的牛皮！！！
3，运行爆显存killed
查看这位大神的，稳！

tip:在我们进行make -jx 编译时，这个x表示运用的并行进程数，我们可以通过
nproc
来查看，这命令会返回你的CPU核心数，这通常可以作为 x 的最大值。
4.no module named tensorrt
在虚拟环境运行时，虚拟环境不能链接到系统环境的tensorRT8.x包，按照网上教程我本打算配置编译tensort模块，但是失败了，有待研究。

另一个方法，加入系统环境python版本和你的虚拟环境一样,你可以尝试下列方法：
